3.6.2.2.1 Examples

Data elements located at latitude −5.2° and longitude +45.2° will be found under the directory named: \CDB\Tiles\S06\E045 Data elements located at latitude +62.3° and longitude –160.4° will be found under the directory named: \CDB\Tiles\N62\W162 The reason for “W162” instead of “W161” is that at latitudes between 50° and 70°, the CDB Geocells have a width of 2 degrees as indicated in Table 3-29: NbSliceIDIndex for every CDB Zones. “W162” corresponds to the southwest corner of the corresponding CDB Geocell.

3.6.2.3 Directory Level 3 Dataset Directory

The name of the directory at level 3 is composed of the dataset code and dataset name. The complete list is provided in Annex Q of the OGC CDB Core: Model and Physical Structure: Informative Annexes. Examples are provided below.

3.6.2.3.1 Examples

The elevation and the imagery of the geocell located at a latitude of −6° and a longitude of +45° will be found under the directories named: \CDB\Tiles\S06\E045\001_Elevation \CDB\Tiles\S06\E045\004_Imagery The list of geospecific features of the geocell located at latitude +62° and longitude –160° will be found under the directory named: \CDB\Tiles\N62\W160\100_GSFeature The network of roads covering the geocell located at latitude +62° and longitude –160° will be found under the directory named: \CDB\Tiles\N62\W160\201_RoadNetwork The geometry and textures of a geospecific 3D model located at latitude −5.2° and longitude +45.2° will be found under the directories named: \CDB\Tiles\S06\E045\300_GSModelGeometry 115 © 2016 Open Geospatial Consortium \CDB\Tiles\S06\E045\301_GSModelTexture The geometry of tiled 2D models covering the geocell located at latitude −5° and longitude +45° will be found under the directories named: \CDB\Tiles\S05\E045\310_T2DModelGeometry To complete these examples, the files associated with the Navigation dataset and covering the geocell located at latitude +36° and longitude −88° will be found under the directory named: \CDB\Tiles\N36\W088\401_Navigation
